A (Aperture Priority) Mode
You set the aperture yourself and the camera automatically varies the shutter 
speed so that the picture is taken with the correct exposure.
AE (Automatic Exposure)
The camera's built-in exposure meter automatically sets the exposure. The 3 
AE modes available on this camera are P mode, in which the camera selects 
both the aperture and shutter speed, A mode, in which the user selects the 
aperture and the camera sets the shutter speed, and S mode, in which the 
user selects the shutter speed and the camera sets the aperture.
In M mode, the user selects both the aperture and the shutter speed.
Aperture
The adjustable lens opening which controls the amount of light that enters the 
camera. The larger the aperture, the shorter the depth of field and the fuzzier 
the background. The smaller the aperture, the greater the depth of field and 
the sharper the background. Aperture is measured in f/stops. Larger aperture 
values indicate smaller apertures, and smaller aperture values indicate larger 
apertures.
Center weighted averaging metering
A light metering mode or technique that uses an average of the center and 
periphery of the image area but is biased toward the information at the center 
of the image area. This method is best used when the brightness of the center 
and periphery of the image area does not vary greatly. See also digital ESP 
metering and spot metering.
Color space
A model that describes colors using more than three coordinates. Color 
spaces such as sRGB, Adobe RGB are occasionally used for encoding/
reproducing colors.
Color temperature
The spectral balance of different white light sources is rated numerically by 
color temperature 
k a concept of theoretical physics that, with incandescent 
lighting, corresponds roughly to the absolute lamp filament temperature, 
expressed on the Kelvin (K) temperature scale. The higher the color 
temperature, the richer the light in bluish tones and the poorer in reddish; the 
lower the color temperature, the richer the light in reddish tones and the 
poorer in bluish. You may encounter difficulties with color reproduction when 
shooting indoors under fluorescent lighting, or where sunlight and fluorescent 
lighting are both present. Your camera is provided with a white balance 
adjustment feature that you can use to compensate for the odd effects of 
combinations of color you may occasionally see in your pictures.
